Just another quick question Alex  - all is working fine now and have been able to get some users on and posting away - I noticed that if I try to "customize" my Design Protean with new design it causes nginx error "502 bad gateway"  - this happens after changing the design to another Protean style which I have created (PS I have also clear the CSS cache as per instrutions) -- is there anything wrong in the settings that I need to adjust?  - thanks again

Please create separate thread for another problem, and also specify more info, such as php error log, and what you changed particularly.
